<\/a><\/p>\n

8. m\u00e4rtsil toimus m\u00e4lu andmekapitali uuendamine. Memcached<\/strong> versioonini 1.6.0<\/strong>. Peamine erinevus varasematest versioonidest on see, et n\u00fc\u00fcd on v\u00f5imalik kasutada v\u00e4liseadmeid vahem\u00e4lu andmete salvestamiseks.<\/p>\n

Memcached<\/strong> kasutatakse k\u00f5rge koormusega veebisaitide v\u00f5i veebi rakenduste t\u00f6\u00f6 kiirendamiseks, salvestades juurdep\u00e4\u00e4su andmebaasidele ja vaheandmetele.<\/p>\n

Uues versioonis on vaikimisi kompileerimisel aktiivne seade extstore<\/strong>, mis vastutab v\u00e4lise salvestusseadme kasutamise eest. Funktsiooni deaktiveerimiseks tuleks .\/configure-s m\u00e4\u00e4rata parameeter \u2014disable-extstore. Siiski, vaatamata vaikimisi sisse l\u00fclitatud kogumisele, tuleb k\u00e4ivitamisel selgelt n\u00e4idata selle funktsiooni kasutamine.<\/p>\n

Extstore<\/strong> lubab kasutada v\u00e4liseid Flash<\/strong> v\u00f5i SSD<\/strong> salvestusseadmeid vahem\u00e4lu suuruse suurendamiseks. See v\u00f5imaldab salvestada palju suuremaid andmemahtusid kui ilma selle funktsiooni kasutamiseta.<\/p>\n

Veel \u00fcheks oluliseks uuenduseks on v\u00f5rgu interaktsiooni \u00fcmberkujundamine, mis on n\u00fc\u00fcd kohandatud \u00fche s\u00fcsteemi kutsumise raames pakettide automaatseks t\u00f6\u00f6tlemiseks. Eelnevates versioonides edastati iga GET-p\u00e4ringu t\u00f6\u00f6tlemine eraldi paketis, samas kui uues versioonis kogutakse mitme p\u00e4ringu vastused \u00fchte metapaketti ja edastatakse korraga. Selle muudatuse tulemusel v\u00e4henes CPU koormus 25%.<\/p>\n

Selle moderniseerimise tulemusena on ka v\u00e4henenud m\u00e4lu tarbimine puhverdamiseks \u2014 4,5 kb-lt 400-500 baitini kutsumise kohta ning v\u00e4henenud on malloc, realloc ja free funktsioonide kasutamine, mis on viinud enam v\u00e4iksema m\u00e4lufragmenteerimiseni. Iga niit k\u00e4sitleb n\u00fc\u00fcd oma puhverateenuseid aktiivsete \u00fchenduste lugemiseks ja kirjutamiseks. Nende puhvrite suuruse seadmiseks on ette n\u00e4htud valikud -o resp_obj_mem_limit=N ja -o read_buf_mem_limit=N.<\/p>\n

Sama moodi on kuulutatud, et serveriga \u00fchenduse pidamise binaarne protokoll on t\u00f5stetud \"vananenud\" klassi. Selle asemel on kasutusele v\u00f5etud meta protokoll \u2014 tekstiline versioon protokollist koos kompaktsete meta-k\u00e4skudega. Uues protokollis on arvesse v\u00f5etud k\u00f5ik varem saadaval olnud toimingud, mis kasutasid vana versiooni binaarsest protokollist.<\/p>\n
